Abstract: Using the monitoring data from 517 public service forest plots in the central area of Zhejiang Province in 2010-2011, the carbon storage and carbon density of the public service forest were evaluated based on the calculated biomass of different communities. The results showed that the average biomass of the public service forest was 99.30 t·hm^-2, the present total biomass was 16 430.40× 10⁴ t, the average carbon density was 49.59 t C·hm^-2, and the total carbon storage was 8 205.59×10⁴ t C in central Zhejiang. The analysis also demonstrated that the carbon density was significantly affected by stand age and density. Finally, this study established a model, C b = aA + bD + c ,which was composed by stand age and density to estimate the carbon density of the public service forest in central Zhejiang for improving the public welfare forest carbon sequestration ability.

Key words: public service forest, biomass, carbon storage, carbon density, the central area of Zhejiang Province
